Due to the continuous growth of the Internet, current internet communication protocol (IPv4) is no longer sufficient for the future. The Next generation Internet Protocol (IPv6) brings the solution for the long predicted limitations of IPv4. But the resistance to change from IPv4 is hindering the adoption of IPv6. In Africa, IPv4 is still in use and as a result affecting the acceptance of IPv6. These research work analysed the factors affecting IPv6 adoption in Nigeria by conducting a survey for enterprise organizations to understand their deployment approach and challenges faced. Many organizations indicated insufficient technical skills, lack of training programs, cost of upgrade etc. as key factors affecting IPv6 deployment. Further investigation was conducted by some world renowned organizations based on their IPv6 deployment strategies and five key phases were discovered to be used. A simulation experiment of dual-stack and 6to4 tunneling mechanism was conducted to understand how IPv4 and IPv6 co-exist simultaneously and how the gradual transition takes place.

Cette thèse traite de l’adaptation automatique des applications sensibles au contexte par l’utilisation d’informations liées à l’environnement social des utilisateurs afin d’enrichir le service rendu par les applications. Pour cela, notre contribution s’articule autour de la modélisation multidimensionnelle des différents niveaux de contextes sociaux, notamment le poids de la relation entre les acteurs. Plus spécifiquement, nous synthétisons des contextes sociaux non seulement liés à la familiarité mais aussi liés à la similitude des communautés statiques et dynamiques. Deux modèles basés respectivement sur les graphes et les ontologies sont proposés afin de satisfaire l’hétérogénéité des réseaux sociaux de la vie réelle. Nous utilisons les données réelles recueillies sur les réseautages sociaux en ligne pour conduire nos expérimentations et analysons les résultats en vérifiant l’efficacité de ces modèles. En parallèle nous traitons le point de vue de l’application, et nous présentons deux algorithmes utilisant des contextes sociaux pour améliorer la stratégie de transmission des données dans le réseau opportuniste, et particulièrement la contre-mesure aux nœuds égoïstes. Les simulations des scénarios réels confirment les avantages liés à l’introduction des contextes sociaux, en termes de taux de succès et de délais de transmission. Nous effectuons une comparaison avec d'autres algorithmes de transmission traditionnellement décrits dans la littérature pour compléter notre démonstration

Purpose – The aim is to investigate concepts that are used in depicting future visions of society, as afforded by technology, to (a) map the extent of their use, (b) examine the level of their dominance in different research areas and geographic boundaries, (c) identify potential overlaps, (d) analyse their longitudinal growth, and (e) examine whether any of the identified concepts has assumed an overarching position.
Design/methodology/approach – Fourteen concepts, each of which is used to depict visions of future information infrastructures, were identified. More than 20,000 scholarly documents related to eleven of these concepts (those with 20 or more documents) are analysed by various qualitative/quantitative methods.
Findings – The two concepts most referred to are semantic web and ubiquitous computing (all years), and internet of things” (year 2013). Publications on some newer concepts (e.g. “digital living”, “real world internet”) are minimal. There are variations in the extent of use and preferred concepts based on geographic and disciplinary boundaries. The overlap in the use of these terms is minimal and none of these terms has assumed an overarching umbrella position.
Research limitations/implications – This study is limited to scholarly publications; it would be relevant to also study the pattern of usage in governmental communications and policy documents.
Social implications – By mapping multiplicity of concepts and the dispersion of discussions, we highlight the need for, and facilitate, a broader discussion of related social and societal implications.
Originality/value – This article is the first to present a collective of these related concepts and map the pattern of their occurrence and growth.

Networks must transition to new internet protocol IPv6, that have larger address pool however it has limitations that hinder its growth. IPv6 addresses will solve alote of interent problems in the earlier version protocol and it provides new opportunities. However, due to the increased overhead in IPv6 and it " s interaction with the operating system that hosts this communication protocol, there may be network performance issues. This paper will focus on the considerations that affect network performance analysis for IPv4 and IPv6 based networks for ubuntu12.0.4 and Windows 7 Operating Systems deployed on top of a virtual infrastructure. Virable data size (KByte, MByte and GBit) were used to compare two internet protocols. Two virtual computers are configured with the two versions of IP and empirically evaluated for performance difference. Performance related metrics like throughput, delay, and jitter are measured on virtual test-bed implementation.
... ISPs are considering a shift from IPv4-IPv6. IPv4 protocol has the capability to migrate to IPv6 within a short period [2,9]. It costs too heavy and does not allow the interruption of the service, and damage to critical distributed applications. ...
The Internet is migrating from IPv4 (Internet Protocol version 4) to IPv6 (Internet Protocol version 6).
The high cost of migration services from IPv4-IPv6 and system complexity are main factors for slow
adaption of IPv6 This paper presents the implementation of migration techniques from IPv4-IPv6.
Furthermore, existing IPv4 addresses have already been depleted in IANA (Internet Assigned Numbers
Authority) and will be soon exhausted in RIR (Regional Internet Registry) while more clients are
joining the Internet. Slower rate of the progress of IPv6 confirms complete shifting from IPv4-IPv6 at
once is still long away, although fewer parts of IPv6 have been employed in current market goods.
Integration of IPv4 and IPv6 is carried in order to take care of online users. In this paper, it is suggested
that hierarchical direction finding structural design in IPv4 and IPv6 will improve the efficiency of IPv4
network. This research work provides the way to design the network scenario for the carrier grade set
of connections. The carrier grade network scenario routers are named to be Karachi, Sukkur, Islamabad,
Multan and Peshawar for the managerial simulation purposes. The carrier grade network deployment
is implemented along with dual stack to migrate to IPv6. This study holds the way to deploy IPv4-IPv6
carrier grade network by providing real time scenario which is yet not considered in the literature to
the best of our knowledge

Last few decades has brought many fundamental changes to data communications and the Internet. Internet has its roots in a networking project started by ARPA which consisted of four computers. Now the Internet spans the globe, and has become the default communication mechanism for businesses and individuals. IPv4 addresses will soon be exhausted, which has initiated development of IPv6. The new IP version provides solution to problems that were inherent in the earlier version, and also offers additional opportunities. However transition to the new version has been remarkably slow. Thus in the interim, various transition mechanisms can be employed.

The potential exhaustion of IPv4 addresses initiated the development of IPv6. The new version of the Internet Protocol offers substantially more network and host addresses, however transition from current to the new version has been remarkably slow. There are multiple reasons for the sluggish transition: complexity and enormousity being the forerunners. Thus for the interim, various transition mechanisms have been developed. Each mechanism has its associated benefits and weaknesses. In this paper two such mechanisms, namely configured tunnel and 6to4 transition mechanism, have been empirically evaluated for performance. Both mechanisms are implemented on two different Windows Server operating systems and performance related metrics like throughput, delay, jitter and CPU usage of the transition end nodes are measured. The results obtained on the test-bed show that TCP/UDP throughput and jitter values of the two mechanisms are similar, but delay and CPU reading are significantly different depending on the choice of transition mechanism and operating system.
Depleting IPv4 addresses has generated enormous interest in the new version of Internet Protocol, IPv6. It was developed by Internet Engineering Task Force (IETF) to completely replace IPv4. However, due to many reasons, migration to the new version of the Internet has been slow. For the interim, various transition mechanisms have been developed. This research examines and empirically evaluates the performance of two such transition mechanisms, namely 6to4 and configured tunnel when implemented on network infrastructure. Performance metrics like throughput, jitter and delay are measured for these transition mechanisms. This research shows that 6to4 transition mechanism gives better network performance than configured tunnel.
Simulation modeling of computer networks is an effective technique for evaluating the performance of network and data transfer with various internet protocols. In this paper we are focusing on the impact of used transport layer protocol transferred with new internet protocol (IPv6) against network performance, especially network router load and efficiency. Higher values of load or worse efficiency can be a problem in global IPv6 deployment. We propose methodology of traffic measurement based on different stochastic systems. We are able to generate different TCP, UDP and SCTP traffic according to uniform probability distribution for packet inter departure time and packet size. We use a generator that is able to reproduce experiment by using the same seed for random values and we focus on the correlation of packet size, inter departure time to router and communicating nodes load. All experiments were made in pure IPv4 environment and in native IPv6 environment too. We expected that the use of a new protocol lead to higher efficiency of data transfer. By using forward stepwise regression analysis we identify which variables imply the packet transfer time.
